Foxy coffee {Queensland Agr. Jour., 8 {1901), No. 5, pp. 370-371).— ''This term 

 denotes a reddy-brown appearance of the seed caused by the adhesion of the silver 

 skin into which the coloring matter in the outer skin and fruity portion of thecherry 

 has infiltrated." This appearance indicates that the fruit was picked when quite 

 ripe. It does not injure the quality of the coffee, though it is undesirable from the 

 standpoint of appearance. Some precautions which should be taken to prevent foxy 

 coffee are suggested as follows: 



" (1) Avoid, as far as possible, allowing the berries to become dead, or purple, ripe 

 on the trees. They should be picked as uniformly red-ripe as possible. A spot of 

 green on the outside pulp will make no difference, the bean being nearly alwa3's 

 matured before the pericarp has been fully colored. 



" (2) Pulp the coffee as soon after taking in as possible. The operations of pulping 

 and measuring might go on simultaneously. ... 



"(3) Pulp as cleanly as possible. If pulpers are not working satisfactorily, this 

 must be done with the aid of a sieve, the skins and half-pulped cherry being passed 

 through the pulpers a second time. 



"(4) Wash the coffee as soon as the mucilage is ready to be acted on by water. 

 This can be determined by experiment."

The horticultural status of the genus Vaccinium, W. M. Munson {Maine Sta. 

 Bui. 76, pp. 113-160, figs. 9). — This paper aims to present as concisely as may be the 

 exact status of the genus Vaccinium at the close of the nineteenth century and to 

 give greater publicity to the horticultural worth of blueberries. The distribution of 

 the species is noted, horticultural notes given on the uses of the fruits, the ornamental 

 value of some varieties pointed out, methods of propagation and cultivation detailed, 

 descriptions given of the blueberry industry in Maine and elsewhere in the United 

 States, and a key to the natural groups of species. The future outlook for the blue- 

 berry industry is also discussed. A bibliography of 44 references to literature on 

 blueberries, huckleberries, cranberries, etc., completes the bulletin. 



The report on the blueberry industry in Maine has been noted earlier (E. S. R., 11,
